Application filed. June 28, 1923.. Serial No. 648,353.

To aZZ whom it may concern:

Be it known that 1, JOHN REGAN, a citizen of the United States, residing at New Bedford, in the county of Bristol and State of Massachusetts, have invented a new and useful lVarp-Stop-li fotion Clamp, of which the following is a specification.

This invent-ion relates to a clamp designed for use in connection with the general type of stop motion shown in my prior Patent No. 1,265,112 issued May 7, 1918. When this type of stop motion is used in broad looms it is found desirable to provide lateral support for the vibrator bars and drop wire spacing bars at one or more intermediate points, so that lateral or swinging movement of the bars may not interfere with the operation of the stop motion and furthermore so that the weight of the relatively small vibrator bars may not cause the bars to bend or sag excessively between their end supports. Clamps for this general purpose are shown in my prior Patents No. 1,307,022, issued June 17 1919, and No. 1,355,909, issued October 19, 1920.

It is the object of my invention to imrove the. clamp shown in my prior Patent No. 1,307,022 by certain changes in the c0nstruction thereof which will be hereinafter,

described and more particularly pointed out in the appended claims.

A preferred form of my invention is shown in the drawings in which Fig. 1 is a side elevation of my improved clamp, the vibrator and spacing bars of a stop motion being shown in section;

Fig. 2 is a sectional elevation taken along the line 22 in Fig. 1; and

Fig. 3 is a sectional plan. view taken along the line 3-3 in Fig. 1.

Referring to the drawings, 1 have shown my invention as applied to a six bank stop motion having six vibrator bars 10 and seven separator bars 11. The drop wlres W are positioned as indicated by dotted lmes in Fig. 1, the different banks of wires being separated by the bars 11, and each w re is provided with an opening through which extends one of the vibrator bars 10.

For further details of the construction and operation of the stop motion, reference is made to my prior patent above noted.

My improved warp stop motion clamp comprises a center member 12, and an upper clamping bar 13 and lower clamping bar 14.- both pivoted to the member 12. The member 12 is provided with slots or recesses 15" ment in the usual operation of the stop motion.

A hook bolt 18 extends through a lug or ear 19 on the bar 13, the hook end 20 of the bolt 18 being received in a notch 21 in the lower edge of the lower clamping bar 14. A nut 22 is threaded on the bolt 18 and provides means for drawing the parts firmly together. The bars 13 and 1 1 are pivoted to projecting portions 23 of the member 12 and the bar 13 is preferably provided with'depending spaced projections 25 (Fig. 2) adapted to embrace the upper edge of the member 12 and the lower bar 14 is similarly provided with upwardly extending projections 26 (Fig. 1) for the same purpose. The provision of theseprojections 25 and 26 assists greatly in laterally aligning the parts and preventing dislocation thereof. The upper face of the bar 14 is preferably widened at 27 to provide an additional bearing surface under the end separator bar 11 as the clamping pressure is largely applied at this point.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed otherwise than as set forth in the claims but what I claim is 1. A warp stop motion clamp comprising a center member, upper and lower clamping bars pivoted to said center member, and means to bind said parts together, certain of said parts having spaced projections at their free ends embracing other parts to preserve the lateral alignment thereof.

2. A warp stop motion clamp comprising a center member, upper and lower clamping bars pivoted to said center member, and means to bind said parts together, said lower bar and said center member having co-opera'ting portions near their free ends eiiective to laterally align said parts when in clamping position.

8. Warp stop mot-ion clamp comprising a center member, upper and lower clampilw bars pivoted to said center member, and means to bind said parts together, said upper and lower bars having spaced projections embracing said center member When the parts are drawn together and preserving the lateral alignment thereof.

4. A Warp stop motion clamp comprising a center member, upper and lower clamping bars pivoted to said center member, and means to bind said parts together, said center member and said upper member having co-opera-ting recesses in their adjacent edges forming substantially circular openings for the vibrator bars of the stop motion.

5. A Warp stop motion clamp comprising a center member, upper and lower clamping bars pivoted to said center member, and means to bind said parts together, said lower member having a portion of its upper bar-supportingface substantially widened adjacent its free end to provide increased bearing surface for the outside separator bar supported thereby,

.In testimony whereof I have hereunto aflixed my signature.

JOHN REGAN.
